Description
Technical Field
The present disclosure relates to a shielded connector and an outer conductor terminal.
Background
The shielded connector disclosed in patent document 1 includes: an inner conductor terminal (terminal fitting); a dielectric body which accommodates the inner conductor terminal; and an outer conductor terminal (outer conductor) that houses a dielectric module composed of the inner conductor terminal and a dielectric. The outer conductor terminal has an insertion port on a rear surface and integrally has a lid portion that is displaced to an open position and a closed position by a hinge (boundary line) connected to an opening edge of the insertion port. The dielectric module is inserted into the module receiving portion of the outer conductor terminal when the cover is located at the open position.
On the other hand, the shielded connector disclosed in patent document 2 includes an inner conductor terminal, a dielectric body that houses the inner conductor terminal, and an outer conductor terminal that houses the dielectric body, and the outer conductor terminal includes a lid body that covers a dielectric insertion opening on a rear surface and is separate from an outer conductor terminal main body.

Problems to be solved by the invention
In the case of patent document 1, since the outer conductor terminal has a hinge at the coupling portion of the cover, the notched portions located on both sides of the hinge inside the slack portion become gaps, and there is a possibility that noise caused by a high-frequency signal leaks or enters from such gaps, and the shielding performance is impaired. Further, the presence of the cap makes it difficult to perform an operation of detecting a state in which the terminal component is soldered to the circuit board.
On the other hand, in the case of patent document 2, since the cover body which is a separate body can cover the entire dielectric insertion port, the shielding performance can be improved, and the cover body can be mounted after the connection state of the terminal parts is detected. However, the lid body of patent document 2 is box-shaped and merely fitted into the rear portion of the outer conductor terminal main body from the outside, and therefore may come off from the outer conductor terminal main body.
Therefore, an object is to provide a shielded connector and an outer conductor terminal capable of improving shielding performance and assemblability.
Means for solving the problems
The shield connector of the present disclosure includes: an inner conductor terminal; a dielectric body that houses the inner conductor terminal; and an outer conductor terminal that houses the dielectric body, the outer conductor terminal including: an outer conductor terminal main body having an insertion port for the dielectric body on a rear surface thereof; and a cover member attached to the outer conductor terminal main body and separate from the outer conductor terminal main body, the outer conductor terminal main body having a locking receiving portion on each side surface, the cover member including: a back portion covering the insertion opening; and a pair of side portions connected to the back portion and covering respective side surfaces of the outer conductor terminal main body, the pair of side portions having locking portions that lock with the locking receiving portions.
Effects of the invention
According to the present disclosure, a shielded connector and an outer conductor terminal capable of improving shielding performance and assemblability can be provided.

Detailed Description
[ description of embodiments of the present disclosure ]
First, embodiments of the present disclosure will be described.
The shielded connector of the present disclosure is provided with a shield connector,
(1) the disclosed device is provided with: an inner conductor terminal; a dielectric body that houses the inner conductor terminal; and an outer conductor terminal that houses the dielectric body, the outer conductor terminal including: an outer conductor terminal main body having an insertion port for the dielectric body on a rear surface thereof; and a cover member that is attached to the outer conductor terminal main body and is separate from the outer conductor terminal main body, the outer conductor terminal main body having a locking receiving portion on each side surface, the cover member including: a back portion covering the insertion opening; and a pair of side portions connected to the back portion and covering respective side surfaces of the outer conductor terminal main body, the pair of side portions having locking portions that lock with the locking receiving portions.
In the case of the separate cover member, the back portion can cover the entire insertion opening of the outer conductor terminal main body, and therefore shielding performance can be improved. Further, the cover member may be attached to the outer conductor terminal main body after detecting the state of soldering or the like of the terminal component. Further, the locking portions of the pair of side portions are locked to the locking receiving portions in the side surfaces of the outer conductor terminal main body, so that the cover member can be stably attached to the outer conductor terminal main body and can be prevented from falling off from the outer conductor terminal main body.
(2) The outer conductor terminal body may have a 2 nd locking receiving portion on a surface other than each side surface, the cover member may have a covering portion covering the surface other than each side surface of the outer conductor terminal body, and the covering portion may have a 2 nd locking portion locked to the 2 nd locking receiving portion. The 2 nd locking portion of the covering portion is locked to the 2 nd locking receiving portion, so that the cover member is further stably assembled to the outer conductor terminal main body.
(3) The covering portion may also be erected between the pair of side portions. If the side portion is cantilevered from the back portion, the side portion may deform about a connecting portion with the back portion as a fulcrum, and the locking portion may fall off from the locking receiving portion. However, according to the above configuration, since the covering portion is provided between the pair of side portions, the deformation of the side portions can be prevented by the covering portion, and the state in which the locking portion is locked to the locking receiving portion can be maintained satisfactorily.

The housing base 27 can house the outer conductor terminal body 15 in the terminal housing 26.
As shown in fig. 1 and 2, the case base 27 has a pair of protection walls 32 protruding rearward on both sides. In a state where the outer conductor terminal main body 15 is inserted into the terminal accommodating portion 26, the 3 rd connecting portion 24 of each inner conductor terminal 12 protrudes rearward from the terminal accommodating portion 26, and the protection walls 32 are positioned on both sides across the protruding portion, thereby protecting each inner conductor terminal 12.
The housing 13 has a pair of mount mounting grooves 33 (only one is shown in fig. 1) in portions of both side surfaces that straddle the housing base 27 and the cover 28. The rear end of each mount mounting groove 33 is defined by each protection wall 32. The housing 13 is soldered and fixed to the surface of the circuit board 90 by the fixture 30 pressed into each fixture mounting groove 33 from above. The fixing member 30 is a metal plate.
(outer conductor terminal body 15)
The outer conductor terminal body 15 is formed by punching out a plate base material and then bending the plate base material into a predetermined shape. As shown in fig. 4 and 5, the outer conductor terminal main body 15 includes a top plate portion 34, a pair of side plate portions 35, and a bottom plate portion 36. The top plate 34 and the bottom plate 36 face each other in the vertical direction, and the side plates 35 face each other in the width direction (the left-right direction). As shown in fig. 4, the bottom plate portion 36 has a butt end portion 37 at a widthwise central portion. The outer conductor terminal main body 15 is restricted from opening by engaging the mating end 37 of the bottom plate 36 in a dovetail fit-like concave-convex manner, and can maintain its box shape.
The outer conductor terminal main body 15 has a dielectric housing 38 penetrating in the front-rear direction inside defined by the top plate 34, the side plates 35, and the bottom plate 36. The dielectric housing 38 is formed in a rectangular shape in cross section, and as shown in fig. 11, has a pair of dielectric locking receiving portions 39 protruding inward by tapping on both side surfaces. The rear surface opening of the dielectric housing 38 is configured as an insertion port 41 for inserting the dielectric body 11 into the dielectric housing 38. The dielectric body 11 is elastically locked to the dielectric body locking receiving portion 39 by the dielectric body locking portion 21, and is held in the dielectric body accommodating portion 38 so as to be prevented from coming off.
The outer conductor terminal body 15 has a pair of outer conductor locking portions 42 protruding outward by striking on each side plate portion 35. As shown in fig. 4 and 6, the outer conductor locking portion 42 and the dielectric locking receiving portion 39 are provided in the side plate portion 35 in a front-rear arrangement. The outer conductor terminal body 15 is elastically locked to the outer conductor locking receiving portion 31 of the housing 13 by the outer conductor locking portion 42, and is held in the terminal accommodating portion 26 of the housing 13 so as to be prevented from coming off.
The outer conductor terminal main body 15 includes an elastic contact piece 43 bent inward between U-shaped notches at the front portion of each side plate portion 35 and the front portion of the top plate portion 34, and a pair of embossed portions 44 (see fig. 5) extending in parallel in the front-rear direction on the side of the bottom plate portion 36 facing the elastic contact piece 43 of the top plate portion 34. When the outer conductor terminal main body 15 is connected to the female terminal fitting of the counterpart, the embossed portions 44 abut against the counterpart outer conductor terminal of the female terminal fitting, and the elastic contact pieces 43 elastically contact with the counterpart outer conductor terminal, whereby both terminal fittings are shielded and connected.
As shown in fig. 4, the outer conductor terminal main body 15 has a pair of locking receiving portions 45 at the rear portion of each side plate portion 35. Each locking receiving portion 45 is a hole penetrating the side plate portion 35 in the thickness direction, and is formed in a rectangular opening shape having a lower edge that is linear along the front-rear direction, as shown in fig. 6. The corners of both upper corners of each locking receiving portion 45 are rounded into an arc shape, and the corners of both lower corners of each locking receiving portion 45 have a rectangular corner. As shown in fig. 6, the locking receiving portion 45 is located at the center portion in the vertical direction of the side plate portion 35, and is arranged at the same height as the elastic contact piece 43, the outer conductor locking portion 42, and the dielectric locking receiving portion 39 of the side plate portion 35.
As shown in fig. 4 and 6, the outer conductor terminal main body 15 has a cutout portion 46 communicating with the dielectric housing portion 38 at the rear portion of the bottom plate portion 36 and opened downward and rearward. The outer conductor terminal main body 15 has a protrusion piece 47, which is a rectangular plate as seen from the front end of the notch 46 and extends by being bent downward, and a pair of connection pieces 48, which are L-shaped as seen in side view, which are bent downward and extend from the rear end of the bottom plate 36 on both sides of the notch 46 and are further bent rearward. The extension of each connecting piece 48 extending rearward is disposed along the surface of the circuit board 90 and soldered to the shield circuit of the circuit board 90.
As shown in fig. 4 and 5, the projecting piece 47 has a large area portion 51 and a small area portion 52 on both sides of the butt end portion 37, and a 2 nd locking receiving portion 49 is provided in a central portion of the large area portion 51. The 2 nd locking receiving portion 49 is a hole penetrating the projecting piece 47 in the thickness direction, and is formed in an opening shape having a rectangular shape with a lower edge formed linearly along the front-rear direction, and has substantially the same shape as each locking receiving portion 45.
(cover member 16)
The cover member 16 is formed by punching out a single flat plate base material, bending the punched plate base material into a predetermined shape, and the like, in the same manner as the outer conductor terminal main body 15. As shown in fig. 7 and 8, the cover member 16 integrally includes: a back 53 which is rectangular in shape at the rear along the vertical direction and the width direction; a pair of side portions 54 extending in the vertical direction and the front-rear direction and protruding forward from both side ends of the back portion 53; and a covering portion 55 that is bridged between the front ends of the pair of side portions 54, and the cover member 16 is formed into a rectangular frame shape in plan view.
The back portion 53 has a flat plate surface without front and rear irregularities, and is configured to have a size covering the entire insertion port 41 of the outer conductor terminal main body 15 (see fig. 17).
Each side portion 54 is connected to both side ends of the back portion 53 over the entire height, and is disposed so as to intersect (more specifically, be orthogonal to) the plate surface of the back portion 53. As shown in fig. 7, each side portion 54 is formed by cutting a corner of the upper portion of the tip into an L shape, and has: a 1 st piece 56 of a rectangular shape with longitudinal sides, which protrudes forward from both side ends of the back 53; and a 2 nd piece 57 which is a horizontally long rectangle in side view, is continuous with the lower end of the 1 st piece 56, and projects forward. Most of the 2 nd piece 57 is located below the back 53. As shown in fig. 14 to 16, the 1 st piece portion 56 of each side portion 54 can cover a rear portion of the outer surface (each side surface) of each side plate portion 35 of the outer conductor terminal main body 15. The 2 nd piece portion 57 of each side portion 54 can cover the lower portion of the 2 nd connecting portion 23 of each inner conductor terminal 12 and the like from both sides (see fig. 17).
As shown in fig. 8, each side portion 54 has a pair of locking portions 58 protruding inward by striking at the 1 st piece portion 56. Each of the locking portions 58 is triangular in front and rear views, has a lower end disposed horizontally, and is disposed obliquely in a tapered shape from an upper end to a projecting tip end. The locking portions 58 are continuous with the surrounding portions of the 1 st piece 56 without interruption so that the outer surfaces of the 1 st piece 56 of the side portions 54 are recessed (see fig. 18).
As shown in fig. 7 and 8, the covering portion 55 is disposed along the vertical direction and the width direction, as in the back portion 53. The cover 55 and the back 53 are arranged to face each other in a stepped manner. The covering portion 55 has a long portion 61 and a short portion 62 bent inward from the rear end of the 2 nd piece portion 57 of each side portion 54, and abutting edge portions 77 of the long portion 61 and the short portion 62 are engaged with each other in a dovetail fit manner in a concave-convex manner to restrict opening and maintain the frame shape of the lid member 16. The long-sized portion 61 extends from the 2 nd sheet portion 57 by a larger amount (length) than the short-sized portion 62 extends from the 2 nd sheet portion 57.
The covering portion 55 has a 2 nd locking portion 59 protruding inward by tapping in the long portion 61. As shown in fig. 13 and 17, the 2 nd locking portion 59 has a triangular shape in side view, has a lower end disposed horizontally, and is disposed obliquely from an upper end to a projecting tip. In addition, the 2 nd locking portion 59 continues from the peripheral portion of the long-sized portion 61 without interruption in a state where the outer surface (front surface) of the long-sized portion 61 is recessed. In a straightforward manner, the 2 nd locking portion 59 and the locking portion 58 have substantially the same shape.
(method of manufacturing shielded connector 10)
When assembling the shielded connector 10, as shown in fig. 9, the inner conductor terminal 12 is first inserted into each fitting hole 19 of the dielectric body 11. Next, as shown in fig. 11, the dielectric body 11 is inserted into the dielectric body accommodating portion 38 of the outer conductor terminal main body 15 from the insertion port 41, and the dielectric body 11 is fitted to the outer conductor terminal main body 15 so as to be prevented from coming off by locking of the dielectric body locking portions 21 and the dielectric body locking receiving portions 39. As shown in fig. 13, the dielectric body 11 enters the notch 46 of the outer conductor terminal main body 15 through the step 63 protruding from the lower portion and abuts against the rear surface of the protruding piece 47, and thereby stops in the front stop state in the dielectric body housing portion 38 of the outer conductor terminal main body 15. In a state where the dielectric body 11 is mounted on the outer conductor terminal main body 15, as shown in fig. 10, the portions of the inner conductor terminals 12 from the 2 nd connection portion 23 to the 3 rd connection portion 24 are exposed from the dielectric body housing portion 38 and arranged in line with the connecting pieces 48 located on both sides. As shown in fig. 11, the front portion of the 1 st connecting portion 22 of each inner conductor terminal 12 is disposed so as to protrude into the outer conductor terminal main body 15.
Next, the cover member 16 is disposed below the rear portion of the outer conductor terminal main body 15. In this state, as shown in fig. 13, the cover member 16 is inclined so as to tilt the 1 st piece 56 forward, and the 1 st piece 56 is disposed so as to slightly cover the outer surface of the side plate portion 35 of the outer conductor terminal main body 15. Next, the cover member 16 is rotated toward the normal mounting posture so that the covering portion 55 is displaced upward and forward. Then, as shown in fig. 17, the locking portions 58 of the cover member 16 reach positions corresponding to the locking receiving portions 45 of the outer conductor terminal main body 15, and the locking portions 58 are fitted into the locking receiving portions 45 and elastically locked. At the same time, the covering portion 55 of the cover member 16 covers the front surface of the projecting piece 47 of the outer conductor terminal body 15, the 2 nd locking portion 59 of the cover member 16 reaches a position corresponding to the 2 nd locking receiving portion 49 of the outer conductor terminal body 15, and the 2 nd locking portion 59 is fitted into the 2 nd locking receiving portion 49 and elastically locked. Thus, the cover member 16 is stably and reliably attached to the outer conductor terminal main body 15 so as to be prevented from coming off by the locking of the locking portions 58 and the locking receiving portions 45 and the locking of the 2 nd locking portion 59 and the 2 nd locking receiving portion 49. In a state where the cover member 16 is attached to the outer conductor terminal main body 15, the 2 nd connecting portion 23 of each inner conductor terminal 12 and the vertically extending portion of each connecting piece 48 are covered from both sides by the 2 nd piece portions 57 of each side portion 54, and are covered from the front side by the cover portions 55.
In addition, in a state where the lid member 16 is attached to the outer conductor terminal main body 15, the back portion 53 covers and closes the entire insertion opening 41 of the outer conductor terminal main body 15, and as shown in fig. 15 and 16, the 3 rd connecting portion 24 and the extending portion in the front-rear direction of each connecting piece 48 of each inner conductor terminal 12 are disposed so as to be exposed rearward from the lower end of the back portion 53. The back portion 53 and the 2 nd piece portion 57 of each side portion 54 have a step therebetween, and the lower portion of the 2 nd connection portion 23 of each inner conductor terminal 12 and the vertically extending portion of each connecting piece 48 are also disposed in the stepped space 64 due to the step so as to be partially exposed.
Then, the outer conductor terminal body 15 is inserted into the terminal housing 26 of the housing 13 from behind, and the outer conductor terminal body 15, and even the outer conductor terminal 14, is fitted to the housing 13 so as to be prevented from coming off by the engagement of the outer conductor locking portions 42 and the outer conductor locking receiving portions 31. As shown in fig. 3, the outer conductor terminal 14 is stopped in the front stop state at the terminal housing 26 of the housing 13 by the covering portion 55 abutting against the rear surface of the wall portion 78 that defines the front end of the terminal housing 26 in the housing 13.
As described above, according to embodiment 1, the cover member 16 that is separate from the outer conductor terminal main body 15 is attached to the outer conductor terminal main body 15, and the entire insertion port 41 of the outer conductor terminal main body 15 is covered and closed by the back portion 53 of the cover member 16, so that it is possible to prevent a gap from being generated in the outer conductor terminal 14, and to improve the shielding performance.
Even if the cover member 16 is a separate body, the locking portions 58 and the locking receiving portions 45 are locked to hold the outer conductor terminal body 15 in a slip-off manner, and thus the cover member is not accidentally detached from the outer conductor terminal body 15. As a result, the reliability of assembly can be improved.
The outer conductor terminal body 15 has a 2 nd locking receiving portion 49 opened to the front surface of the projecting piece 47, which is a surface other than the outer surface of each side plate portion 35 opened to each locking receiving portion 45, the cover member 16 has a covering portion 55 covering the front surface of the projecting piece 47, and the covering portion 55 has a 2 nd locking portion 59 elastically locked to the 2 nd locking receiving portion 49. Therefore, the cover member 16 is held by the outer conductor terminal main body 15 with higher reliability by adding the locking of the 2 nd locking portion 59 and the 2 nd locking receiving portion 49 to the locking of the locking portions 58 and the locking receiving portions 45.
Further, since the covering portion 55 is integrally provided between the pair of side portions 54, the deformation of the side portions 54 about the connecting portion with the back portion 53 as a fulcrum can be prevented, and the state in which the locking portions 58 are locked to the locking receiving portions 45 can be maintained well.
< example 2>
Fig. 19 and 20 show an outer conductor terminal 14A according to example 2. The outer conductor terminal 14A is made of metal in the same manner as in example 1, and includes an outer conductor terminal main body 15A and a cover member 16A that is separate from the outer conductor terminal main body 15A, and the respective forms are different from those of example 1.
The outer conductor terminal body 15A has the same basic configuration as the outer conductor terminal body 15 of example 1, and includes a top plate portion 34A, a pair of side plate portions 35A, and a bottom plate portion 36A, and a dielectric housing portion (not shown) penetrating in the front-rear direction therein. However, the outer conductor terminal body 15A is formed by casting, forging, or cutting, not by press working as in the outer conductor terminal body 15 of example 1. Therefore, the outer conductor terminal main body 15A has no abutting end portion and is continuous over the entire circumference without interruption, and has a structure excellent in shielding performance.
The outer conductor terminal body 15A has a pair of locking receiving portions 45A extending in a groove shape in the vertical direction at the rear portion of the outer surface of each side plate portion 35A, and a rib-shaped protrusion 66 extending in the front-rear direction and perpendicular to the locking receiving portions 45A at the lower end of the locking receiving portions 45A.
The outer conductor terminal main body 15A has a 2 nd locking receiving portion 49A extending in a groove shape in the width direction at a rear portion of the outer surface of the top plate portion 34A. The corner portions 67 at the rear ends of the outer conductor terminal main body 15A are located between the ends of the 2 nd locking receiving portion 49A and the upper ends of the locking receiving portions 45A.
The cover member 16A integrally has: a flat plate-shaped back portion 53A capable of covering the entire insertion opening (not shown) of the outer conductor terminal main body 15A; a pair of bent plate-shaped side portions 54A that protrude short forward from both ends of the back portion 53A and that can cover the rear outer surfaces of the side plate portions 35A of the outer conductor terminal main body 15A; and a folded plate-shaped covering portion 55A that protrudes from the upper end of the back portion 53A in a short distance forward and that can cover the rear portion of the outer surface of the top plate portion 34A of the outer conductor terminal main body 15A. Here, the cover member 16A is a press-formed product, and is therefore formed thinner than the outer conductor terminal main body 15A which is a cast product or the like.
Each of the side portions 54A and the covering portion 55A is capable of flexural deformation about a portion connected to the back portion 53A as a fulcrum, and has a pair of notched escape portions 68 allowing both flexural deformations therebetween. The respective relief portions 68 of the cover member 16A are disposed to correspond to the corner portions 67 of the outer conductor terminal main body 15A.
Each side portion 54A has a pair of locking portions 58A bent inward in a V shape at a projecting distal end portion, and has a guide portion 69 extending from each locking portion 58A to the distal end. Similarly, the covering portion 55A has the 2 nd locking portions 59A bent inward in a V-shape at the projecting distal end portion, and also has the 2 nd guide portions 71 extending from the 2 nd locking portions 59A to the distal end. Each side portion 54A has a fitting groove 72 at the lower end of the locking portion 58A and the guide portion 69, and the fitting groove 72 extends in a groove shape in the front-rear direction perpendicular to the locking portion 58A and the guide portion 69 and penetrates both ends of the back portion 53A.
At the time of assembly, after the dielectric housing portion 38A of the outer conductor terminal main body 15A is housed, the cover member 16A is covered from the rear side on the outer conductor terminal main body 15A. During the assembly of the cover member 16, the side portions 54A and the covering portion 55A slide on the rear outer surface of the outer conductor terminal main body 15A while being guided by the guide portions 69 and the No. 2 guide portions 71, respectively, and are thereby deformed. When the cover member 16A is normally fitted to the outer conductor terminal body 15A, the side portions 54A and the covering portion 55A are elastically restored, and the locking portions 58A and the 2 nd locking portions 59A are fitted into the locking receiving portions 45A and the 2 nd locking receiving portions 49A, respectively, and locked substantially at the same time. Thereby, the cover member 16A is stably held at the rear portion of the outer conductor terminal main body 15A. Further, the projections 66 of the outer conductor terminal main body 15A are fitted and inserted into the fitting grooves 72 of the cover member 16A in the front-rear direction, whereby the cover member 16A can be restricted from being displaced so as to be inclined along the rear end surface of the outer conductor terminal main body 15A.
In example 2, the outer conductor terminal main body 15A is housed in the terminal housing portion 26 (see fig. 3 of example 1) of the housing 13, the inner conductor terminals 12A are soldered to the conductive circuit of the circuit board, and the cover member 16A can be attached to the rear portion of the outer conductor terminal main body 15A from behind after the detection of the connection state. In addition, unlike the inner conductor terminals 12 of example 1, the inner conductor terminals 12A of example 2 extend linearly downward, and are inserted into through holes of a circuit board and soldered.
